The Pontine Marshes:An integrated study of the origin, history, and future of a famous coastal wetland in Central Italy

The Pontine Marshes (Central Italy) are known for their long drainage history starting early in Roman times and culminating in their reclamation (bonificaintegrale) by the Fascist’s regime under Mussolini, mostly in the 1930s of past century. The geology of this coastal wetland and causes for its drainageproblems received limited attention till recently. We reviewed results from recent studies, identified still existing knowledge gaps and performedadditional research to fill these, to produce a full description of the Holocene history and drainage of these marshes. Massive coring data that servedto map the soils and surficial geology, observations in archaeological excavations, analytical data on soil and sediment characteristics, and radiocarbondatings allowed us to distinguish several phases in this history, with a main break in the early Roman Republican period with the first systematic drainageworks. Earlier, natural processes brought about by sea level rise largely controlled its drainage. Once artificial drainage started, soil subsidence became animportant process, aggravating the drainage problems. The bonifica introduced mechanical drainage, temporarily masking the impacts of subsidence. Wequantified the historical subsidence using DTMs and developed scenarios for the impacts of sea level rise and subsidence in 2100 and 2200, assuming thatthis rise will be mitigated by a coastal defence system and enhanced capacity of the mechanical drainage. Our results demonstrate the important role ofsoil subsidence throughout the history of this wetland and need to include subsidence in scenarios for the impacts of sea level rise

CRMsurv Ontology Specification, version 1.1

CRMsurv is an unofficial but formal extension of CIDOC_CRM, co-developed in the Semafora project. It models and represents essential data points for integrating archaeological survey data. It is curated using OntoME, a tool for community based FAIR formal ontology data management.This ontology extends the CIDOC CRM 6.2 ontology data standard for cultural heritage data in order to provide classes and properties necessary to describe unique aspects of the archaeological survey process. It also makes use of classes and properties of the CIDOC CRM extensions CRMArchaeo 1.4.1 and CRMsci 1.2.3. The ontology is intended to support researchers interested in integrating archaeology survey data using the CIDOC CRM
